Augmenting Reality with Reactive Programming

ABSTRACT

In one or more embodiments, one or more systems, methods, and/or processes may utilize a reactive processing system in an augmented reality (AR) system. The AR system may execute program instructions based on a region of an input video signal and produce an output video signal that includes a first output that includes a video effect from the program instructions. The AR system may determine if the region of the input video signal changes. If so, the program instructions may be executed based on the region of the input video signal and a change of the region of the input video and produce the output video signal that includes the second output that includes the video effect. If not, the output video signal that includes the first output that includes the video effect may continue to be produced.

TECHNICAL FIELD

This disclosure generally relates to augmented reality systems.

BACKGROUND

Augmented reality (AR) can allow virtual objects to be placed in a video stream. For example, AR can augment and/or modify input video with computer-generated sound, video, and/or graphics. In one instance, an AR system can utilize face-tracking software that allows a user to appear to wear a mask that moves with the user's face and/or changes expressions. In another instance, a nod of the user's head can cause the mask to move up and down over the user's face. Consumer-facing offerings like this can drive popularity in AR systems.

Realistic integration of the computer-generated sound, video, or graphics into the input video can be one measure of an AR system. AR systems process various facets of input video, and continually processing the various facets of the input video, regardless of any change or constancy in the input video, can introduce latency into an output video from an AR system. The latency can slow or reduce the integration of the computer-generated sound, video, and/or graphics into the input video.

SUMMARY OF PARTICULAR EMBODIMENTS

In one or more embodiments, one or more systems, methods, and/or processes may utilize a reactive processing system in an augmented reality system. In one example, the reactive system may utilize one or more of a dependency graph and an expression template, among others. In another example, the reactive system may utilize an effects engine that augments one or more video streams with video effects. In one or more embodiments, one or more of facial recognition and object recognition, among others, may provide one or more data bindings (e.g., one or more positions on a person in a video stream, one or more paths along the person in the video stream, etc.) may be utilized in binding functions that produce video effects. For example, the functions that produce video effects may be developed by programmers and uploaded to the reactive system.

In one or more embodiments, data bindings may include time, various parts of a person, a path (e.g., a path along a face, a path along a body, a path along an inanimate object, etc.), and a gyroscope, among others. For example, an application programming interface (API) may permit a programmer to attach a function that produces a video effect to a data binding. For instance, a computer vision process and/or system may provide one or more data bindings to one or more of a face of a person and another portion of the person, among others.

In one or more embodiments, the reactive system may utilize a video input signal, the processed input signal with one or more functions provided by one or more programmers, and provide video output with video effects of the one or more functions provided by the one or more programmers. For example, from video frame to video frame, if the input signal does not change, a function may not be executed, and the output video may remain unchanged. For instance, the reactive system may determine if a portion of the video input signal, that corresponds to a data binding of a function, changes. If the portion of the video input signal that corresponds to the data binding of the function changes, the function may be executed, and one or more of a video effect corresponding to the function may change in an output video signal (e.g., output video stream) and a position of the video effect corresponding to the function may change in the output video signal. If the portion of the video input signal that corresponds to the data binding of the function does not change, a corresponding portion of the output video signal that includes the video effect may not change. In this fashion, less processing in an augmented reality system may be accomplished, according to one or more embodiments. For example, less processing in the augmented reality system may reduce or eliminate latency of the augmented reality system.

DESCRIPTION OF EXAMPLE EMBODIMENTS

In one or more embodiments, an augmented reality system may allow virtual objects (e.g., video effects) to be placed in a video stream. For example, the augmented reality system may augment and/or modify input video with one or more sounds, videos, and/or graphics. In one or more embodiments, the augmented reality system may utilize a reactive processing system in augmenting and/or modifying the input video with the one or more sounds, videos, and/or graphics. In one example, the reactive system may utilize one or more of a dependency graph and/or an expression template, among others. In another example, the reactive system may utilize an effects engine that augments and/or modifies one or more video streams with video effects (e.g., sounds, videos, graphics, etc.). In one or more embodiments, user-provided functions, that produce video effects, may be provided to the augmented reality system and may be bound to data bindings (e.g., one or more feature points, one or more positions on a person in a video stream, one or more paths along the person in the video stream, etc.). For example, the functions that produce video effects may be developed by programmers and uploaded to the augmented reality system.

In one or more embodiments, an application programming interface (API) may permit a programmer (e.g., a software developer) to attach a function, that produces a video effect, to a data binding. For example, data bindings may include time, various parts of a person, a path (e.g., a path along a face, a path along a body, a path along an inanimate object, etc.), and a gyroscopic data binding, among others. For instance, a computer vision process and/or system may provide one or more data binding to a face of a person. In one or more embodiments, one or more systems, processes, and/or methods described herein may accomplish less processing in the augmented reality system. For example, less processing in the augmented reality system may reduce or eliminate latency of the augmented reality system.

In one or more embodiments, from video frame to video frame, if a video input signal does not change, a function that produces a video effect may not be executed, and an output video may remain unchanged. For example, the reactive system, of the augmented reality system, may determine if a video region of the video input signal, that corresponds to a data binding of a function, changes. In one instance, if the video region of the video input signal that corresponds to the data binding of the function changes, the function may be executed, and one or more of a video effect corresponding to the function may change in an output video signal (e.g., output video stream) and a position of the video effect corresponding to the function may change in the output video signal. In another instance, if the video region of the video input signal that corresponds to the data binding of the function does not change, a corresponding portion of the output video signal that includes the video effect may not change.

Turning now to FIG. 1, a video signal and data bindings are provided, according to one or more embodiments. As shown, a video signal 110 may be provided to a recognizer 115. In one or more embodiments, recognizer 115 may include one or more of a facial recognition process, method, and/or system, a computer vision process, method, and/or system, and an object recognition process, method, and/or system, among others. For example, recognizer 115 may receive video signal 110 and process video signal 110 to determine video regions 120A-120D of video signal 110. In one or more embodiments, one or more of video regions 120A-120D may include respective one or more video signal attributes. For example, a video attribute may include a transparency attribute, a color attribute, an intensity attribute, or a transparency attribute, among others.

As illustrated, streaming output 130 may display a person 140. For example, streaming output 130 may be streaming video output, and person 140 may be streaming video output of a person. In one or more embodiments, one or more data bindings may be associated with streaming output. As shown, data bindings 150A-150D may be associated with streaming output 130. For example, data bindings 150A-150D may be associated with person 140.

In one or more embodiments, one or more video regions may be associated with one or more respective data bindings. For example, video regions 120A-120D may be associated with respective data bindings 150A-150D. For instance, one or more video regions 120A-120D may change positions as respective one or more data bindings 150A-150D change positions from video frame to video frame.

In one or more embodiments, recognizer 115 may utilize one or more of data bindings 150A-150D in producing respective one or more video regions 120A-120D. In one example, recognizer 115 may receive video signal 110 and process video signal 110 based on data bindings 150A-150D to determine respective video regions 120A-120D of video signal 110. In one instance, one or more data bindings 150A-150D may change positions from video frame to video frame, recognizer 115 may process video signal 110 based on data bindings 150A-150D, and recognizer 115 may produce respective video regions 120A-120D that change positions from video frame to video frame. In another instance, one or more data bindings 150A-150D may change measurements from video frame to video frame, recognizer 115 may process video signal 110 based on data bindings 150A-150D, and recognizer 115 may produce respective video regions 120A-120D that change measurements from video frame to video frame. In another example, recognizer 115 may receive video signal 110 and process video signal 110 based on data bindings 150A-150D to determine if one or more data bindings 150A-150D changes position or changes measurement. In one instance, recognizer 115 may process video signal 110 and determine that data binding 150A changes position. In another instance, recognizer 115 may process video signal 110 and determine that data binding 150D changes measurement.

In one or more embodiments, streaming output may be augmented. For example, streaming output 130 may be augmented with one or more video effects. For instance, the one or more video effect may be associated with respective one or more data bindings. In one or more embodiments, streaming output 130 may be provided to a network.

Turning now to FIG. 2, a programmable video effects of an effects engine is illustrated, according to one or more embodiments. As shown, an effects engine 210 may utilized program instruction (PI) effects 220A-220D. In one or more embodiments, effects engine 210 may be or include a configurable reactive processing system. For example, effects engine 210 may be configured with PI effects 220A-220D. For instance, effects engine 210 may execute PI effects 220A-220D, and PI effects 220A-220D may receive respective video regions 120A-120D and produce output video effects associated with respective data bindings 150A-150D.

In one or more embodiments, an API may permit a programmer to attach a function that produces a video effect. For example, the function that utilizes the API may be compiled or interpreted to produce a PI effect of PI effects 220A-220D. In one instance, source program instructions (e.g., source code) may include the function, which may be compiled into processor instructions that are executable by a processor. In another instance, source program instructions (e.g., source code) may include the function, which the function may be compiled into processor instructions that are executable by a virtual machine (e.g., a Python virtual machine, a TLC virtual machine, a Lua virtual machine, a Squirrel virtual machine, a Java virtual machine, a VMWare virtual machine, a QEMU virtual machine, etc.).

In one or more embodiments, effects engine 210 may receive one or more of PI effects 220A-220D from a network. In one example, effects engine 210 may not store one or more of PI effects 220A-220D and executes the one or more of PI effects 220A-220D as the one or more of PI effects 220A-220D are streamed from the network. In another example, effects engine 210 may receive one or more of PI effects 220A-220D from the network and store the one or more of PI effects 220A-220D. In one or more embodiments, source program instructions may be received from a network. For example, source program instructions may be compiled to produce one or more of PI effects 220A-220D.

In one or more embodiments, effects engine 210 may include and/or may be implemented by a dependency graph and/or an expression template. In one example, if a video region of video regions 120A-120D does not change, then output from a corresponding PI effect of PI effects 220A-220D does not change. For instance, output from the corresponding PI effect may be maintained in streaming output 130. In another example, if a video region of video regions 120A-120D changes, then a corresponding PI effect of PI effects 220A-220D is executed, and output from the PI effect may augment streaming output 130. For instance, augmenting streaming output 130 with the output from the corresponding PI effect may include augmenting streaming output 130 with the output from the corresponding PI effect at or proximate to a data binding corresponding to the PI effect.

For example, the attribute of the face checker may be data binding 150C. In one or more embodiments, effect 410 may travel along data binding 150C. For example, video effect 410 may appear to fly along path data binding 150C across a face of person 140 in streaming output 130. For instance, a position of video effect 410 along path data binding 150C may be updated and/or changed as an amount of time transpires.

For example, recognizer 115 may determine one or more attributes associated with data binding 150D. For instance, the one or more attributes may include one or more measurements. For instance, recognizer 115 may determine a distance between lips 520A and 520B.

In one or more embodiments, recognizer 115 may include, a computer vision process, such as the face checker, that may determine the one or more attributes associated with data binding 150D. In one example, the computer vision process may determine how much lips 520A and 520B are apart. In another example, a distance between lips 520A and 520B may be utilized in determining how much a mouth of person 140 is open. As illustrated in FIGS. 5A-5C, a video effect 510 may be changed in accordance with how much the mouth of person 140 is open. In one example, a flame (e.g., video effect 150D) may be bigger as more open the mouth of person 140 becomes. For instance, video effect 150D may augment fire breathing to person 140. In another example, the flame (e.g., video effect 150D) may be smaller as less open the mouth of person 140 becomes.

In one example, the user may select video effect 720 with video region 120A as an input. In a second example, the user may select stream element 750 for an output of video effect 720. For instance, stream element 750 may be dragged onto canvas 770 and configured with video region 120A or configured as video region 120A. In a third example, the user may select video effect 740 with video with video stream element 750 as an input. For instance, video effect 740 may include one or more attributes, such as transparency, colors, intensity, etc. In a fourth example, the user may select data binding 760, which may become data binding 150A that may be utilized in augmenting streaming output 130.

At 830, it may be determined if the portion of the video signal changes. For example, effects engine 210 may determine if the video region of video regions 120A-120D changes. If the portion of the video signal does not change, the method may proceed to 825. If the portion of the video signal changes, the program instructions may be executed based on the portion of the video signal and a change of the portion of the video signal at 835. For example, the respective PI effect of PI effects 220A-220D may be executed utilizing the video region of video regions 120A-120D and a change of the video region of video regions 120A-120D. For instance, effects engine 210 may execute the respective PI effect of PI effects 220A-220D utilizing the video region of video regions 120A-120D and the change of the video region of video regions 120A-120D.
